2.5.9.3 Diagnostic Logging and Log Rollover
The Jetty request log file ($VCLOUD_HOME/logs/yyyy_mm_dd.request.log) is programmatically controlled by the Jetty (HTTP) server, but does not come with a maximum size limit. For this reason, there is a risk of unbounded log file growth. A log entry is added to the current file for each HTTP request served by Jetty. VMware recommends that you use log rotate or similar methods to control the size of logs and the number of old log files to keep.
The other diagnostic log files are limited to 400 MB total. Verify that you have sufficient free disk space to accommodate those files plus the size that you allow the Jetty request logs to consume. Centralized logging makes sure that you do not lose valuable diagnostic information as the 400 MB log file total is reached and files are rotated and deleted.
